I have an 86 951 and I have been driving it for about a week now. I parked it last Friday nite and went to start it Sat. morn.It would not start.It turns over just fine, it just doesn't fire. I have fuel, I have spark, but the little critter won't fire.It coughs and sometimes sounds as if it will start, but it doesn't.When it does cough and sputter a bit clouds off gas rich smelling smoke puff out of the exhaust.I put new plugs in because the others were fouled out from trying to start it.It has been raining for the past 20 out of 22 days, but I ruled out wires because I have spark.What else could I check before buying dynamite.

Did you pressure test your fuel rail? If the pressure is to high the injectors won't fire. You can disconnect one injector and if it starts then your FPR might be bad.

 

replace the dme relay and if you have and alarm from the factory check to see if moisture is in the alarm relay box its under the pasanger foot well its black 4 inches long 1 inch wide.

 

I have fuel though. Or should I say that the plugs are coming out covered with fuel.Is possible that the injectors are leaking so much that the car can't start because of too much fuel?
Thanks,

 

It has no alarm that I know of.
